Diffuse pollution of these compounds can be potentially mitigated by the application of green infrastructures, which are a pillar of the EU Green Deal. In this context, a phytoremediation pilot plant was realised and supplied by a contaminated well located in Lonigo Veneto Region, Italy where surface and groundwaters were significantly impacted by perfluoroalkyl acids PFAAs discharges from a fluorochemical factory. The investigation involved the detection of perfluorobutanoic acid PFBA , perfluorooctanoic acid PFOA , perfluorobutanesulfonic acid PFBS and perfluorooctanesulfonic acid PFOS inside the inlet and outlet waters of the phytoremediation pilot plant as well as in reed grasses grown into its main tank. The obtained results demonstrate that the pilot plant is able to reduce up to 50% of considered PFAAs in terms of mass flow without an evident dependence on physico chemical characteristics of these contaminants. Moreover, PFAAs were found in the exposed reed grasses at concentrations up to 13 ng g ww. A positive correlation between PFAA concentration in plants and exposure time was also observed. In conclusion, this paper highlights the potential efficiency of phytodepuration in PFAS removal and recommends improving the knowledge about its application in constructed wetlands as a highly sustainable choice in wastewater remediation. 14 Published version http //www.scopus.com/record/display.url eid=2 s2.0 85127318278 origin=inward articolo articolo 2022_Ferrario_water 14 00946.pdf Articolo in rivista Molecular Diversity Preservation International 2073 4441 Water Basel Water Basel Water Basel Water.
